Safety Considerations
• Read this document for information on installation, handling,
mounting, general product specifications, and operation of this
product. These installation instructions contain important
information on handling the instrument.
• Working safety requires that all safety instructions and work
instructions are observed.
• Observe the relevant local accident prevention regulations and
general safety regulations for the range of use of the instrument.
• The installation instructions are part of the product and must
be kept in the immediate vicinity of the instrument and readily
accessible to skilled personnel at any time.
• Skilled personnel must have carefully read and understood the
operating instructions before any work begins.
• The Bulletin 837T-D is a temperature switch that converts
temperature into an electrical signal indoors and outdoors. The
device has been safely built with state-of-the-art technology and
meets the applicable requirements and EC directives. It can,
however, be a source of danger if used incorrectly or for
anything other than the designated use.
• Qualified individuals are required for installation and
commissioning. Failure to comply results in personal injury or
equipment damage.
• Before installation, commissioning and operation, be sure that
the appropriate temperature switch has been selected in terms of
range of measurement, design, and specific conditions of
measurement.
Recommended Installation for Optimal Performance
a. Installation at angle pieces, against the direction of flow
b. Installation in smaller pipes, which are inclined against the
direction of flow
c. Installation vertical to the direction of flow.

(1) At high medium or ambient temperature, helps confirm (by suitable measures) that the instrument case temperature does not exceed 80 °C (176 ° F) in continuous operation. The temperature is a measured hexagon of the
process connection. At medium temperatures (above 80 °C [176 °F]), the thread must not be immersed into the medium. The permissible ambient temperature is limited to -20…+40 °C (-4…+104 °F) at the high temperature
option.
(2) High temperature models are only available in 100 mm (3.94 in.) or greater probe lengths. It includes compression fitting that is approximately 55 mm (2.16 in.).
(3) The mounting situation (immersion depth, sensor length, operating conditions) determines the accuracy. This situation is especially the case for large temperature gradients between the environment and the mediu m.
(4) Absolute value of temperature.

IMPORTANT For high temperature models, the real probe length, which is
inside the process, is shorter for the version with compression
fitting (high temperature models). This difference is because
55 mm (2.16in.) of the compression fitting length is
subtracted from the total probe length. For example, a probe
length of 150 mm (5.91 in.): 150 mm minus 55 mm
(compression fitting) > 95 mm (3.74 in.), which is inside the
process.

Making the Mechanical Connection
• While mounting, make sure that the sealing faces at the
instrument are clean and undamaged.
• Only screw in or unscrew the instrument via the wrench flats.
Never use the case as a working surface.
• The correct torque depends on the dimensions of the process
connection and the gasket used (form/material).
• When screwing in, be careful not to cross the threads.
Figure 3 - Types of Seals
A correct seal of the process connections with parallel threads at the face
of the seal, must be made using suitable flat gaskets and sealing rings.
The seal of the tapered threads (for example, NPT thread) is made to
provide the thread with additional sealing material such as, PTFE tape
(EN 837-2).
Mating Cables
• 889D – F4AC-2 (M12x1 connector).
• 889D-R4AC-2 (M12x1 right angle connector).

Commissioning
ATT EN TI ON : Only for use with the temperature switch if it is in
perfect condition concerning safety.
Check the following points before commissioning:
• Fluid leakage is indicative of damage.
• Since this switch is a safety-relevant component, check the
diaphragm for any visible damage.
Required tool: Spanner size 27 open-ended spanner and
screwdriver.
Compression Fitting
Follow these steps while mounting the high-temperature model with
compression fittings.
1. Screw the compression fitting (Step 1 in Figure 4
process connection and tighten.
2. Insert the tapered side of the ferrule (Step 2 in Figure 4
fitting and screw the union nut (Step 3 in Figure 4) hand tight.
3. Insert the temperature switch into the fitting and maintain the
required immersion depth. Tighten the union nut (Step 3 in
) with approximately 50 N•m (442.5 lb•in).
Figure 4
ATT EN TI ON : The temperature switch can be damaged at high
temperatures. At medium temperatures above 80 °C (176 °F), be
sure that the distance to the housing (55 mm [2.16 in.]) is
maintained when you mount the compression fitting.
4. Optional: Check the assembly and loosen the union nut. The
ferrule is firmly connected to the sensor tube.

Confirmation of the input
The temperature switch has
two operating modes, the display mode
and the programming mode. The function
of the keys depends on the selected
operating mode.
Enter key: In programming mode, press
the enter key once to set the values for the
selected parameters.
Note: Short press equals three seconds; long press equals five seconds.
Making the Electrical Connection
• The instrument must be grounded via the process connection.
• The power supply for the temperature switch must be made via
an energy-limited electrical circuit in accordance with section
9.3 of UL/EN/IEC 61010-1 or an LPS to UL/EN/IEC 609501 or class 2 in accordance with UL1310/UL1585 (NEC or
CEC). The power supply must be suitable for operation above
2000 m (6561.6 ft) in case the temperature switch is used at this
altitude.
• For cable outlets, make sure that no moisture enters at the cable
end.

Keys and Functions
Dismantle and Disposal
Let the instrument cool down sufficiently before dismantling.
ATT EN TI ON : Residual media in the dismantled temperature
transmitter can result in a risk to persons, the environment, and
equipment. Take sufficient precautionary measures.
BURN HAZARD: Let the instrument cool down sufficiently before
the dismantle process. During the dismantle process, there is a risk
of dangerously hot pressure media escaping.
Incorrect disposal can put the environment at risk.
Dispose of instrument and packaging materials in an environmentally
compatible way and in accordance with the country-specific waste
disposal regulations.
IMPORTANT Short press equals three seconds; long press equals five
seconds.
